Why It's More Difficult To Remember New Information, Especially As We Get Older...

Information Overload...
The older we get, the more difficulty we seem to have remembering things. We can leave our cars in the same parking lot each morning, but unless we park in the same space each and every day, it's a challenge eight hours later to recall where we left the vehicle.

Another common example... We can be introduced to new people at a meeting and will have forgotten their names before the initial handshake. Typically, we reassure ourselves that our brains are just too full to handle the overload of new information that comes in daily.

According to a team of Johns Hopkins neuro-scientists, the real difficulty is that our aging brains are unable to process this information as "new" because the brain pathways leading to the specific area of the brain that stores memories called the hippocampus become degraded over time. As a result of hippocampus degradation, our brains cannot accurately "file" new information (like the names of new people we meet and where we left the car in the parking garage), and we experience confusion.

"Our research uses brain imaging techniques that investigate both the brain's functional and structural integrity to demonstrate that age is associated with a reduction in the hippocampus's ability to do its job, and this is related to the reduced input it is getting from the rest of the brain," said researchers of psychological and brain sciences in Johns Hopkins' Krieger School of Arts and Sciences. "As we get older, we are much more susceptible to "interference" from older memories than we are when we are younger."

When faced with an experience similar to what it has encountered before, such as parking the car, our brain tends to recall old information it already has stored instead of filing new information and being able to retrieve that. Thus, you can't find your car immediately and find yourself wandering the parking lot."Maybe this is also why we tend to reminisce so much more as we get older: because it is easier to recall old memories than make new ones," the researchers explained.

The study appears in the May 9 online edition of the "Proceedings of the National Academy of Sciences"
The Johns Hopkins team used MRI scans to observe the brains of 40 healthy young college students and older adults, ages 60 to 80, while these participants viewed pictures of common, everyday objects and classified each (by pressing a button) as either "indoor" or "outdoor." (The team used three kinds of MRI scans in the study: structural MRI scans, which detect structural abnormalities; functional MRI scans, which
document how hard various regions of the brain work during tasks; and diffusion MRIs, which monitor how well different regions of the brain communicate by tracking the movement of water molecules along pathways.)

Some of the pictures were similar but not identical, and others were markedly different. The team used functional MRI to watch the hippocampus when participants saw items that were exactly the same or slightly different to ascertain how this region of the brain classified that item: as familiar or not.

"Pictures had to be very distinct from each other for an older person's hippocampus to correctly classify them as new. The more similar the pictures were, the more the older person's hippocampus struggled to do this. A young person's hippocampus, on the other hand, treated all of these similar pictures as new," they explained.

Later, the participants viewed a series of completely new pictures and again were asked to classify them as
either "indoor" or "outdoor." A few minutes later, the researchers presented the participants with the new set
of pictures and asked whether each item was "old," "new" or "similar.""The 'similar' response was the critical response for us, because it let us know that participants could distinguish between similar items and knew that they're not identical to the ones they had seen before," they said. "We found that older adults tended to have fewer 'similar' responses and more 'old' responses instead, indicating that they could not distinguish between similar items."

The inability among older adults to recognize information as "similar" to something they had seen recently is linked to what is known as the "perforant pathway," which directs input from the rest of the brain into the hippocampus. The more degraded the pathway, the less likely the hippocampus is to store similar memories as distinct from old memories.

"We are now closer to understanding some of the mechanisms that underlie memory loss with increasing age," according to the researchers. "These results have possible practical ramifications in the treatment of Alzheimer's disease, because the hippocampus is one of the places that deteriorate very early in the course of that disease."

The team's next step would be to conduct clinical trials in early Alzheimer's disease patients using the mechanisms that they have isolated as a way to measure the efficacy of therapeutic medications.

"Basically, we will now be able to investigate the effect of a drug on hippocampal function and pathway integrity," they noted. "If the drug slows down pathway degradation and hippocampal dysfunction, it's possible that it could delay the onset of Alzheimer's by five to 10 years, which may be enough for a large proportion of older adults to not get the disease at all. This would be a huge breakthrough in the field."

The study was funded by the National Institute on Aging.

Rhodiola For Increased Mental Energy And Concentration: This Herb Just May Be The Perfect Focus-Factor!

Rhodiola for whatever ails you? The Book “Rhodiola Revolution” says that this one European herb is scientifically proven to: “maximize energy; fight the effects of stress and aging; sharpen memory and concentration; ease anxiety and depression; and enhance physical performance.” How in the world can one herb do all this you ask? Well, the good news is like many botanical ingredients today, there is a scientific explanation that shed’s a bright light on the benefits of this fascinating herb.

Rhodiola rosea (R. rosea or rhodiola) has been utilized medicinally for centuries in many European and Asian countries, where it grows in the unusually harsh environment of polar, Arctic, and high-altitude alpine regions.1 Between 1725 and 1960, various medicinal applications of rhodiola appeared in the scientific literature of many countries, including Sweden, Norway, France, Germany, the Soviet Union, and Iceland.2 Since 1960, more than 180 modern pharmacological, phytochemical, and clinical studies have been published.2

Although rhodiola has been extensively studied in other countries and shown to exhibit multiple health-promoting effects, its properties are largely unknown in the United States. In part, this is likely due to the fact that the bulk of research has been published in Slavic and Scandinavian languages.2 During the Cold War, a strict wall of separation – in communication, politics, and science – was maintained by the Soviet Union. Research regarding rhodiola was one of the casualties of this information roadblock, as much of the research occurred in Russia and appeared in Russian medical journals. The data from many of these studies have been under wraps until recently, when they began to appear in limited venues.3,4

As you are no-doubt aware, the past 10 to 20 years have witnessed an explosion in the scientific study of herbal and nutritional supplement formulations. You have also probably noticed that until very recently, much of this research took place in western Europe — particularly in Germany, where their unique medical system evaluates the safety and indications of herbs that are prescription items, sold or dispensed in pharmacies.3 Other countries involved in extensive herbal and nutritional research include Sweden, Italy, China, Japan, India, and Russia.3

Early on, Soviet researchers identified rhodiola as an adaptogen1 – an agent that increases one’s resistance to biological, chemical, and physical stressors. Rhodiola was studied extensively to evaluate its potential benefits for military personnel, cosmonauts, and athletes participating in international competition. Today, an impressive body of scientific literature supports the traditional and modern applications of this herb.

Rhodiola has demonstrated a remarkable ability to enhance cellular energy metabolism. The studies published thus far show the herb to be highly beneficial for both physical and mental performance under stress. The herb provides significant enhancement of mental energy and eliminates fatigue. It stimulates norepinephrine, dopamine, and serotonin, and has cholinergic effects in the central nervous system. Rhodiola also supports and enhances the effects of these neurotransmitters by increasing the delivery of precursors (building blocks) that can be utilized to produce dopamine and serotonin.2,5-9

Much like ginkgo biloba, rhodiola is supported by centuries of documented medicinal uses. Decades of accumulated scientific studies validate rhodiola’s usefulness for improving mental performance, energy, and stamina.

* Protects the nervous system against oxidative damage by free radicals through its antioxidant activity.2,10,11

* Enhances learning and memory in animal models and increases serotonin levels in the frontal cerebral cortex.2,7-9,12

* Promotes release of norepinephrine, dopamine, and serotonin in ascending pathways that activate the cerebral cortex and the limbic system. Consequently, the cognitive (thinking, analyzing, evaluating, calculating, and planning) functions of the cerebral cortex and the attention, memory, and learning functions of the prefrontal and frontal cortex are enhanced.2

* Optimizes the release of acetylcholine, the neurotransmitter associated with learning, attention and memory.2

* May prevent or ameliorate some age-related dysfunction in neurotransmitter systems that tend to deteriorate with aging.2,13

* Has been found, in animal studies, to improve long-term memory when administered in low doses over a period of 10 days.8

* Has been found to positively influence the central nervous system by increasing ability to concentrate and by improving cellular resistance to outside influences.14

Rhodiola Rosea, Stress, And Mental Performance
Stress interferes with memory functions. Over time, stress causes deterioration in memory systems. Rhodiola rosea (R. rosea or rhodiola) appears to exert positive effects on memory and cognition by improving resistance to physical and emotional stress.

This dual action of cognitive stimulation and emotional calming creates benefits for immediate cognitive and memory performance, as well as for the long-term preservation of brain function.2 Calm and alert – you can’t be in a better mental state than that!

* Several studies have shown that rhodiola (again specifically: R. rosea) can dramatically reduce stress and simultaneously increase mental performance. One study found that a 170 mg/day dose of rhodiola countered the fatigue and stress experienced by young, healthy physicians on night duty.15 In this randomized, double-blind, and placebo-controlled trial, researchers measured rhodiola’s effect on five different measures of mental acuity: associative thinking, short-term memory, calculation, concentration, and speed of audiovisual perception. They found statistically significant improvements in all five of these mental performance parameters in the physicians who took rhodiola for two weeks.15

* In a double-blind, placebo-controlled trial conducted at a medical academy, young, healthy students were supplemented with either rhodiola (100mg/day) or a placebo for 20 days. The group that consumed the rhodiola extract experienced significant improvements in physical work capacity, coordination, and general well-being, along with decreased mental fatigue and situational anxiety. The supplemented students also scored higher on final exams!16

* A randomized, double-blind, placebo-controlled, parallel-group clinical study was performed to measure the effect of a single dose of rhodiola extract on capacity for mental work against a background of fatigue and stress. Researchers administered a single dose of rhodiola to healthy young individuals (19 to 21 years of age) and measured the beneficial results using an anti-fatigue index. The study showed a pronounced anti-fatigue effect from that single dose that was statistically highly significant (p < 0.001).17

In summary: based on centuries of use – going back almost 2,000 years to its documented tradition as a remedy in classic Greek medicine, all the way to the many animal and human clinical studies mounted by modern scientists – we know that rhodiola has a wide array of documented health benefits. In fact, rhodiola is likely to become the next herbal superstar.

Rhodiola’s ability to increase mental energy points to tremendous potential for counteracting the mental fatigue so common with the aging process. And studies show that rhodiola can favorably support our minds and bodies as we deal with the stresses that seem omnipresent in our modern lives. Rhodiolais a valuable addition to any supplement program designed to boost mental performance and slow the aging process.

Richard P. Brown and Patricia L. Gerbarg, astute researchers who have worked tirelessly in bringing the science behind this unique herb to Western medicine, had this to say:

In the course of evolution, R. rosea has adapted to the harsh conditions of high altitude (extreme cold, low oxygen, little rainfall, and intense irradiation from the sun) by producing a group of powerful protective compounds that have diverse beneficial effects in animals and humans. One is struck by the versatility of R. rosea, from its description in Greek medicine, 2000 years ago to its use by 20th century cosmonauts. It is time for modern research, using controlled clinical trials, to develop the potential medical applications of this unique phyto-adaptogen.3,4

In their exhaustive review of the medical and scientific literature exploring the benefits of this wonderful herb, the authors go on to say that

…[m]ore scientific research is needed to confirm the preventive and curative benefits of R. rosea. Controlled studies are warranted to explore its use in antidepressant augmentation, disorders of memory and cognition, attention deficit disorder, traumatic brain injury, Parkinson's disease, protection against arrhythmias, sports performance, aviation and space medicine (enhancing physical and mental performance while reducing stress reactions), endocrine disorders (infertility, premenstrual disorder, menopause), sexual dysfunction, disorders of the stress response system (fibromyalgia, chronic fatigue syndrome, and post traumatic stress disorder), and enhancement of chemotherapy/radiation with amelioration of toxicity.2

How To Take Rhodiola

Rhodiola rosea root extract is commonly available as an individual supplement and in combination products. If you choose a combination product, take as directed on the label. For the individual herb, typical doses are 150 to 300 mg/day of extract, taken in two divided doses on an empty stomach. For example: 150 mg before breakfast and 150 mg before lunch, for a total of 300 mg/day.2
It’s most important to look for a Rhodiola rosea root extract standardized to contain a minimum of three percent rosavins and one percent salidroside. This matches the extract concentrations used in clinical trials.

Be sure to specifically look for Rosea. Products called just "Rhodiola,” “Tibetan Rhodiola,” or “Indian Rhodiola” are NOT equivalant to Rhodiola rosea root extract. In fact, because of significant species-dependent variations in phytochemistry, the use of "Rhodiola" alone as a general term may be inaccurate and could be misleading on product packaging. Of all the species tested, Rhodiola rosea has been the predominant subject of phytochemical, animal, and human studies.2

While clinical studies have shown a benefit in taking doses higher than 300 mg/day of Rhodiola rosea root extract, studies frequently demonstrated that lower doses performed better than higher doses.

Contraindications

First and foremost, Rhodiola rosea is extremely safe, and has very few side effects. Most users find that it improves their mood, energy level, and mental clarity. Some individuals, particularly those who tend to be anxious, may feel overly activated, jittery, or agitated. If this occurs, try a smaller dose with very gradual increases.2
Rhodiola rosea should be taken early in the day. If taken late in the day or evening, it can interfere with sleep or cause vivid dreams (not nightmares) during the first few weeks of use. It is contraindicated in excited states.2
Because Rhodiola rosea has an activating, antidepressant effect, it should not be used in individuals with bipolar disorder who are vulnerable to becoming manic when given antidepressants or stimulants.2
